FIG. 6 is a flowchart showing a general operating procedure of the card conveying device 104 of the reader printer according to an embodiment of the present invention.

First, the CPU 210 initializes the drive circuit, detection device, etc. (step S601). And sensor 147
is ON, that is, whether insertion of the aperture card AP in the manual card feed section 121 is detected (S602).

If insertion of aperture card AP is detected (S6
02: YES), execute the manual feeding subroutine (
S603).

Thereafter, it is determined whether to execute this program again (S617).

If you want to execute it again (YES in S617), step 5
Return to 601. On the other hand, if you do not want to run it again (No),
Exit this main program.

Further, as a result of the determination in step 5602, if the insertion of the aperture card AP is not detected (No), one of the selection buttons on the operation panel 120 is pressed to transport one sheet (S).
W201) is pressed (step 5604).

If the single sheet transport button 5W201 is pressed, execute the single sheet transport subroutine S605), step 561
Proceed to step 7. This is a case where one aperture card AP is transported from the card loading section 122 to the right tray 123 via the carrier (projection position).

Can be used to search for cards.

Next, if the single sheet transport button 5W201 is not pressed (No in step 5604), the single sheet transport button 5W
202 is pressed (step 5606).
). If 5W202 is pressed, the left tray transport subroutine is executed (5607), and then step 5617 is executed.
Proceed to. By pressing this button 5W20.2, one aperture card ap is transported from the left tray 24 to the carrier (projection position).

If NO in this step 5606, that is, if the single sheet transport button 5W202 is not pressed, the process advances to the next step 5608. In step 8608, it is checked whether the automatic transport button 5W203 has been pressed. When the automatic transport button 5W203 is pressed, the print operation flag FlagA is set to 1 (no print operation) 5609), and after the automatic transport subroutine is executed (S610), the print operation flag FlagA is set to 0 (no print operation). ) and reset it to (
5611), proceed to step 5617.

When this automatic transport button 5W203 is pressed, the aperture card AP is automatically and continuously transported from the card loading section 122 to the carrier (projection position), but printing is not performed and only the reader operation is performed. It is possible to continuously scan a large number of aperture cards AP.

Further, if the automatic transport button 5W203 is not pressed, then it is checked whether the automatic transport button 5W204 is pressed (step 5612). This button 5
If W204 is pressed, after executing the automatic transport subroutine (S610), the print operation flag F1agA is
Please reset to 0 (printing works) 5611),
Execute step 5617. In this case, the automatic conveyance of the aperture card AP is accompanied by a printing operation.

Next, in the case of No in step 5612, it is checked whether the backward conveyance button 5W205 has been pressed (step 5613). If pressed, execute the backward transport subroutine (5614), and then proceed to step 5617. In this subroutine processing, one aperture card AP in the right tray 123 is sent to the carrier (projection position).

If 5W205 is not pressed, it is checked whether the conveyance hold button 5W206 has been pressed (step SS15). If this button 5W206 is pressed, the hold transport subroutine is executed (S616), and the process advances to step 5617.

In this case, the aperture card mill carrier (projection position)
It is conveyed from there to the left tray 124.

For example, it is used when scanning aperture cards AP one by one and distinguishing between necessary cards and unnecessary cards. If the card is needed, it can be stored in the left tray 124 by pressing this button 5W206.

Next, the operating procedure of the manual feed subroutine (executed in step 5603 above) will be explained using FIG.

When this card insertion is detected, from the state where the aperture card ap is supplied to the projection position 111 by the first conveyance means 131, first, by turning on the solenoid 144, the applying member 143 is moved out of the main conveyance path 133. It is evacuated (S701). Along with solenoid 137
is turned on to separate the glass plates 111, 111 from each other (S702). This is to release the pinching pressure of the aperture card ap.

Next, the conveyance rollers 139, 146, and 145 are simultaneously rotated in the normal direction (rotated clockwise in FIG. 3) (S703).
), the aperture card ap held between the glass plates 111, 111 is discharged to the right tray 123. At the same time, the aperture card ap manually fed and inserted from the manual card feeding section 121 is supplied into the main conveyance path 133.

Then, the aperture cart ap is conveyed along the main conveyance path 133 to the position of the sensor 138, and when this sensor 138 detects the aperture card ap (S704), the conveyance rollers 139, 145, 14
The normal rotation of No. 6 is stopped (S705). The reason why the sensor 138 waits for the roller to stop for a predetermined time after detecting the aperture card ap is to ensure that the card ap completely passes the position of the applying member 143.

Then, the solenoid 144 is turned OFF and the applying member 143 is entered into the main conveyance path 133 (S70B
).

Next, the conveying rollers 139, 145, and 146 are reversed (counterclockwise in FIG. 3) to convey the aperture card ap to the position of the applying member 143 (S707). When the aperture card ap contacts the application member 143, the driving of the conveyance rollers 139, 145, 146 is stopped (S708). In other words, the aperture card ap is positioned at the projection position.

Then, the solenoid 137 is turned off to sandwich the aperture card ap between the two glass plates 111 (S709). Thereafter, the microfilm image of the aperture card AP is projected onto the screen 102 or printed.

Next, the operating procedure of the one-sheet transport subroutine (executed in step 5605 above) will be explained using FIG.

First, by turning on the solenoid 144 with the aperture card ap at the projection position shown in FIG. 3, the application member 143 is retracted out of the main conveyance path 133 (5801).

Then, the conveying collages 139, 145, and 146 are rotated in the normal direction (clockwise in the figure) (S802). As a result, the aperture card ap held between the glass plates 111, 111 is ejected to the right tray 123.

Next, it is detected whether the sensor C1 is ON or not, and it is determined whether the aperture card ap remains in the card loading section 122 (S803). As a result of the judgment, if there is no aperture card ap in the card loading section 122 (CI is 0)
FF), proceed to step 5810.

On the other hand, if the aperture card ap remains in the card loading section 122 (S803: YES), the solenoid 1
42 is turned on (5804). Turn solenoid 142 to O
If N, the driven roller 140 is separated from the conveying roller 139 by -28 mm via the arm 141, and the aperture card ap can be supplied from above during this time.

Then, from the card loading section 122 to the first conveyance means 131
For example, the aperture card ap is supplied into the main conveyance path 133 via the conveyance path 34 (FIG. 14) (S8
05).

When the supply of the aperture card ap is detected (3806), the solenoid 142 is activated after a predetermined period of time has elapsed.
is turned off (S807).

Next, the conveyance roller 139 is stopped after a predetermined time (58
08). The aperture car Fap is transported within the main transport path 133 to the right end position after being supplied.

Thereafter, the conveyance roller 139 is reversed (counterclockwise in FIG. 3), and the aperture card ap is brought into contact with the applying member 143 (S809). Then, the conveyance roller 139
(S810).

In other words, the aperture card ap is positioned at the projection position.

Then, turn off the solenoid 137 (S811)
. An aperture card AP is held between two glass plates 111, 111. The film image on this aperture card AP is then projected onto the screen 102 or printed.

Next, using FIG. 9, the left tray transport subroutine (SW
202 is turned on) will be explained. This is a case where a card is transported from the left tray 124 to the right tray 123.

First, the lift-up member 156 of the right tray 123 is lowered (opening the frontage to the tray 123) (S901).

This is to put the aperture card ap into a state where it can be stored in the right tray 123. And solenoid 14
4, the applying member 143 is retracted out of the main conveyance path 133.

Next, the conveyance rollers 139, 145, 146 are rotated normally (third
clockwise in the figure), and the aperture card ap held between the glass plates 111 and 111 is discharged to the right tray 123 (S902).

Next, the sensor 127 provided on the left tray 124 is detected, and it is determined whether the aperture card ap is present on the left tray 124 (S903).

As a result of the determination, if the aperture card ap does not exist (No in S903), the lift-up member 150 of the left tray 124 is lowered (S913), and the process advances to step 5911.

On the other hand, if the aperture card ap exists in the left tray 124 (S903: YES), the solenoid 1
44 is turned on (S904). This is to retract the applying member 143 out of the main conveyance path 133.

Next, the lift-up member 150 of the left tray 124 is raised (S905). As a result, the aperture card ap in the left tray 124 has one end attached to the pickup roller 151.
The preparation for carrying out the aperture card ap is completed.

First, it is determined whether the stop button 5W207 has been pressed (S100I).

As a result of the determination, if the stop button 5W207 is not pressed (No), it is checked whether the sensor C1 provided in the card loading section 122 is ON (S1002).

This is to determine whether or not there is an aperture card ap in the card loading section 122.

As a result of this determination, if there is an aperture card ap in the card loading unit 122 (YES in S1002), execute the single-sheet transport subroutine (31003), and determine whether the print operation flag FlagA is 1 (S1004).
. In other words, it is determined whether or not to perform a printing operation.

As a result of this judgment, if no printing operation is performed (S
1004: YES), the process is executed again from step 51001. On the other hand, when a print operation is to be performed, after the print operation is executed (S l 005), the process is executed again from step 81001.

On the other hand, as a result of the determination in step 51002, if there is no aperture card ap in the card loading section 122 (S1
002 (No), it is determined whether the sensor 154 provided on the left tray 124 is ON (51008). This is to check whether there is a card in the holding tray 124.

As a result of this judgment, the aperture card a is placed in the left tray 124.
If p exists (YES in S1006), after executing the left tray transport subroutine (S1007), step 5
Proceed to step 1004. This step 51002, 51006
means that priority is given to card supply from the card loading section 122.

On the other hand, as a result of the determination in step 51006, the left tray 12
If there is no aperture card ap in 4 (No)
, return to the main program.
